Embodiment Construction

[0036]The present invention is directed to an interchangeable shaft system for connecting the shaft of a golf club to a club head. Such a system can be utilized to provide for customized fitting of various shaft types to a club head and / or to provide adjustability between a shaft and a club head. Several embodiments of the present invention are described below.

[0037]A golf club incorporating an interchangeable shaft system 10 of the present invention generally includes a shaft 12, a shaft sleeve 14, a club head 16 and a fastener 18. Interchangeable shaft system 10 may be used by club fitters to repeatedly change shaft 12 and club head 16 combinations during a fitting session. The system permits fitting accounts maximum fitting options with an assembly of parts that is easy to use. In an embodiment, after a desired shaft 12 and club head 16 combination is selected, interchangeable shaft system 10 may be semi-permanently fixed so that disassembly by the average consumer is prevented. ...

Abstract

A golf club incorporating an interchangeable shaft system includes a shaft, a shaft sleeve, a club head and a fastener. The shaft sleeve is coupled to an end of the shaft and is received in a hosel included in the club head. The fastener retains the shaft sleeve in the hosel. Hosel and shaft sleeve alignment features are provided that provide discreet orientations between the shaft and club head.

Description

FIELD OF THE INVENTION[0001]This invention generally relates to golf clubs, and more specifically to golf clubs having an improved connection between the shaft and club head that provides interchangeability.BACKGROUND OF THE INVENTION[0002]In order to improve their game, golfers often customize their equipment to fit their particular swing. In the absence of a convenient way to make shafts and club heads interchangeable, a store or a business offering custom fitting must either have a large number of clubs with specific characteristics, or must change a particular club using a complicated disassembly and reassembly process. If, for example, a golfer wants to try a golf club shaft with different flex characteristics, or use a club head with a different mass, center of gravity, or moment of inertia, in the past it has not been practical to make such changes. Golf equipment manufacturers have been increasing the variety of clubs available to golfers. For example, a particular model of ...
